Generalized Fubini instantons
A. A. Yurova, A. V. Yurov
We show that nonlinear Klein-Gordon equation with negative coupling admits an exact solution which appears to be the linear superposition of the plane wave and the nonsingu…
The Darboux Transformation and Exactly Solvable Cosmological Models
A. V. Yurov, S. D. Vereshchagin
We present a simple and effective method for constructing exactly solvable cosmological models containing inflation with exit. This method does not involve any parameter fitting. W…
The semiclassical tunneling probability in quantum cosmologies with varying speed of light
A. V. Yurov, V. A. Yurov
In quantum cosmology the closed universe can spontaneously nucleate out of the state with no classical space and time. The semiclassical tunneling nucleation probability can be est…
Complex field as inflaton and quintessence
A. V. Yurov
We investigate cosmology with complex scalar field. It is shown that such models can describe two stages of inflation and the oscillatory regime. Thus we don't need both quintessen…
Tachyonic Instability and Darboux Transformation
A. V. Yurov
Using Darboux transformation one can construct infinite family of potentials which lead to the flat spectrum of scalar field fluctuations with arbitrary multiple precision, and, at…
Brane World Models And Darboux Transformations
A. V. Yurov
We consider a 5-D gravity plus a bulk scalar field, and with a 3-brane. The Darboux transformation is used to construct some exact solutions. To do this we reduce the system of equ…
